Unfortunately what you are asking for is totally blue sky speculation and extemely slim chance of finding the kind of 'room' your asking for. One drill core thru a 'vein' should not be used to forecast such a result.
Overall it's hard to image Windfall not turning into an extremely profitable mine. Just don't expect or advise that Bulk sampling and underground sampling is going to return hugh dollars.
I'll also take exception to ' Just like every other grade Mr. Nemis has pulled out of the ground.' as there have been a good number, as one would expect of 'dud' cores.
Noront has had exceptional and unexpected drill results. Started looking for zinc and found nickel, look for more nickel and find exceptional chromium. Now the 'luck' is being backed up by experianced managment 'to die for' and that combination can't fail.
